    Habit
    Perennial. Culms scandent; 300-2000 cm long; 20-50 mm diam.; woody; without nodal roots. Culm-internodes terete; solid; 22-38 cm long; smooth, or scaberulous. Culm-nodes flush with internodes; with distinct supra-nodal ridge. Lateral branches dendroid; infravaginal. Bud complement 50-80. Branch complement many; in a clump; with subequal branches; thinner than stem. Culm-sheaths deciduous but leaving a persistent girdle; 10-25 cm long; 2 times as long as wide; smooth; hairy on margins. Culm-sheath ligule 1-3 mm high. Culm-sheath blade triangular; demarcated but persistent; erect; 1.4-8 cm long; pubescent and with ciliate margins. Leaves 2-5 per branch. Leaf-sheaths keeled; glabrous on surface; outer margin hairy. Ligule an eciliate membrane; 0.7-1.5 mm long; glabrous on abaxial surface, or pubescent on abaxial surface; truncate, or obtuse. Collar with external ligule; glabrous. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.1-0.2 cm long. Leaf-blades linear; 9-39 cm long; 3-7 mm wide. Leaf-blade venation without cross veins. Leaf-blade surface pilose; hairy abaxially. Leaf-blade margins cartilaginous; scabrous.
    Inflorescences
    Inflorescence a panicle. Panicle open; linear; 7-18 cm long. Primary panicle branches appressed; 4-5 cm long. Panicle axis angular; scabrous. Panicle branches angular; scabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels angular; 1.5-5 mm long; scabrous.
    Spikelets
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 8.8-11.8 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 8.8-11.8 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.5-0.9 mm long; membranous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 5-8.4 mm long; without keels; 0 -veined. Upper glume primary vein absent. Upper glume lateral veins absent. Upper glume apex obtuse, or acute.
    Florets
    Basal sterile florets barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret ovate; 5-8.4 mm long; chartaceous; 3-5 -veined; scabrous; ciliolate on margins; fringed above; acute. Lemma of upper sterile floret ovate; 7.6-11 mm long; chartaceous; scabrous; ciliate on margins; acute. Fertile lemma ovate; 7.9-10 mm long; coriaceous; without keel; 7 -veined. Lemma surface scabrous; inner surface pubescent. Lemma margins ciliate; hairy above. Lemma apex acute. Palea 7.4-9.1 mm long; 4-6 -veined. Palea surface scabrous; pilose; hairy on margins.
    Flowers
    Lodicules 3; 1-1.4 mm long; membranous; ciliate. Anthers 3; 2.3-4.1 mm long. Stigmas 2.
    Fruits
